Colin Young-Wolff/Invision for Hard Rock Cafe/AP Images The cause behind the tragic death of former Stone Temple Pilots and Velvet Revolver singer Scott Weiland has been revealed. According to the Hennepin County Medical Examiner's Office, Weiland died of an overdose from a combination of several drugs, including ecstasy and cocaine, and alcohol. The examiner also found that Weiland's medical history played a role with heart disease and asthma noted as "significant" conditions. His bout with drug addiction and resulting "multi-substance dependence" was also a contributing factor. Although Xanax, sleeping pills, Viagra, and prescriptions to treat bipolar disorder were found on the bus, they were not listed on the report as playing a factor in his death.

The late singer's ex-wife shared an emotional letter with the public in the wake of his passing. "[The] truth is, like so many other kids, they lost their father years ago. What they truly lost on December 3rd was hope," she wrote. "Let's choose to make this the first time we don't glorify this tragedy with talk of rock and roll and the demons that, by the way, don't have to come with it. Skip the depressing T-shirt with 1967-2015 on it - use the money to take a kid to a ballgame or out for ice cream."
